Review Meta Analysis Comparative Study
Does cruciate-retaining total knee arthroplasty enhance knee flexion in Western and East Asian patient populations? A meta-analysis.
This study analyzed the published data to examine if CR TKAs can enhance the flexion and functional outcomes of the knee in the Western and East Asian populations using a meta-analysis approach. ⋯ The meta-analysis indicated that contemporary CR TKAs have not been shown to enhance post-operative flexion capability in the Western and East Asian. The extension angles of the knee and the knee scores were significantly improved in both populations.

Despite the excellent total knee arthroplasty (TKA) results reported using traditional outcome measures, dissatisfaction rates of up to 30% are reported following surgery. Although several preoperative factors have been identified as possible predictors of satisfaction, there is conflicting evidence. Identification of dissatisfaction in the early postoperative assessment may therefore be an alternative consideration. ⋯ Dissatisfaction following TKA is associated with worse outcomes as early as 3months following surgery, with minimal further improvement subsequently achieved at 12-months. Early postoperative assessment following TKA should therefore be considered, including clinical assessment, to identify those patients at risk of dissatisfaction.

There is conflicting evidence as to whether diabetes mellitus influences the functional outcome and patient satisfaction after a total knee replacement (TKR). The aim of this study was to assess the effect of diabetes upon the Oxford knee score (OKS), short form (SF)-12, and patient satisfaction after TKR. ⋯ prospective cohort study, level III.

Comparative Study
Osteochondral scaffold reconstruction for complex knee lesions: a comparative evaluation.
The primary aim of the present study is to evaluate the results obtained in challenging knee lesions with the implant of an osteochondral scaffold and concomitant treatment of all comorbidities. The secondary aim is to compare the results obtained with those found when a chondral scaffold was applied. ⋯ Comparative study.

Comparative Study
The predictors of outcome in total knee arthroplasty for post-traumatic arthritis.
The outcomes of total knee arthroplasty (TKA) for post-traumatic arthritis are less reliable than for idiopathic osteoarthritis. These patients tend to be younger, present with varying degrees of deformity, and often have a history of prior surgery, resulting in a wide spectrum of pathology. We hypothesized that preoperative variables, in particular the location of deformity, would predict pain and functional outcomes. ⋯ IV-Retrospective Case Series.
